NEWTON S. BEALE, OF TAMA, IOWA.

CORN-CRIB VENTILATOR.

SPZEGIFIGATXON forming part of Letters Iatent No. 684,781, dated October 22, 1901. Application filed February 28,1901. Serial No. 49,185. (No model.)

To all whomit may concern:

Be it known that I, NEWTON S. BEALE,a citizen of the United States, residing at Tama, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Corn-Crib Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide for the complete ventilation of corn-cribs of any form by the use of racks adapted to form open spaces through the corn from one side of the crib to the other.

The invention comprises a portable rack adapted to serve as a ventilator, the nature of which will appear from the description and claims following, reference being had to the accompanying drawing, which presents a sectional view in perspective of a ventilator embodying my invention as applied to a corncrib of a conventional type.

In the drawing, A designates a corn crib, which need not be particularly described. It may be said, however, that my invention is designed more especially for use in connection with wide corn-cribs, though the crib shown is rather narrow than otherwise. The ventilator might, indeed, be used in a barn or other like structure having openings communicating with the ventilators, and when emptied of corn the ventilators may be set aside and the barn be used, for other purposes.

In the drawing two types of ventilators are illustrated, alike in principle, but differing in construction. The smaller one, B, is de signed for comparatively low cribs and comprises a base .13, to which are attached pairs of standards B converging at the upper end. To these are nailed longitudinal boards or slats B which slats extend down the standards part way from the upper ends. The

open space below gives room for shoveling. The larger ventilator is made double, so as to give ventilation at two levels. The lower part is similar to the small ventilator just described. To each base and standard is secured an upright or post 13, with a space between them, as shown. This space at the top is roofed over with two boards B and at the sides are attached slats B.

In filling the crib the corn spreads over the floor, covering the bases of the ventilators and filling in between them up to the level of the bottom slat. This serves to hold them in position during the subsequent filling, during which the corn is piled up outside the ventilators, leaving an open air-space within to communicate with the outer air through the sides of the crib. When the upper ventila= tor is reached, the corn piles up in the same manner, and an air-shaft is made near the upper part of the crib. By this means the corn may be piled to practically any desired depth without danger of sweating, since the ventilators may be carried to any desired height and as frequently as may be required. Being portable and .adapted to be set on a floor anywhere without fastening, they are conveniently applied in any suitable place and when not in use may be set aside. Turned bottom up the smaller one would serve very well as a manger.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. A corn-crib ventilator, comprising two or more trestles provided each with a base, and slats secured to the upper parts of said trestles, substantially as described.

2. A corn-crib ventilator, comprising two or more trestles, each provided with a base, a pair of posts secured to each trestle some distance apart, and slats secured to the upper portions of both the posts and trestles, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NEWTON S. BEALE.
